erAck··on German state moving 30k PCs to LibreOffice
> The link is just about a move from one part of Munich to another (MS German HQ has always been in Munich).

Nope. They moved from Unterschleißheim (administrative district of Munich in Upper Bavaria) to Schwabing (district of Munich town), which tax-paying wise makes the difference.

erAck··on Scientists rename human genes to stop MS Excel from misreading them as dates
And actually it depends on the locale you work in whether SEPT is a valid month abbreviation or not.
erAck··on Scientists rename human genes to stop MS Excel from misreading them as dates
SEPT-2 is changed to date (that is how all major spreadsheet software works if an input is accepted as date), SEPT2 is kept as text as entered.
erAck··on Scientists rename human genes to stop MS Excel from misreading them as dates
> if they had a "scientific mode" to not be smart with your data

That "scientific mode" is called text. Assign the column type Text during CSV import and nothing is converted to numeric or date.

erAck··on Scientists rename human genes to stop MS Excel from misreading them as dates
LibreOffice Calc: "SEPT-2" is a date, "SEPT2" is not.
erAck··on Out of all major energy sources, nuclear is the safest (2017)
So we need 4400 persons falling off a roof to be par with nuclear power plants. I still consider this ratio a much better outcome than a power plant going off anywhere near (radius to be defined in Mm depending on wind direction).
erAck··on Out of all major energy sources, nuclear is the safest (2017)
With the difference that one person dropping dead from a roof hurts one family, a nuclear plant going off spoils a huge area for generations.
erAck··on Out of all major energy sources, nuclear is the safest (2017)
Whether solar and wind power are major energy sources depends on where in what region you live.
erAck··on Out of all major energy sources, nuclear is the safest (2017)
They did not include any numbers on wind, solar, hydro, tide, ... renewable energy; limiting the comparison to "the dominant" energy sources what they call "all major energy sources" shows how narrow the researchers' plate is.

World hydro power generation has already a greater percentage than nuclear fission, not in the U.S. though.. Add other renewable resources and all renewable surpass gas. Oil plays almost no role in energy generation. See https://en.wikipedia.org/wiki/Electricity_generation#Methods...

Lovely. Thanks!
erAck··on Guidelines for writing readable code
Try to "simply follow" when it's nested twelve levels deep.

Anyhow, with both approaches, nested or early return, the reader has to read the function from the beginning (or read back until the relevant part) to grasp when exactly a code portion will be executed. In both cases, all if's are relevant, there's no guessing.

erAck··on Stencila: An open source office suite for reproducible research
Regarding your fraction example there:

=RAWSUBTRACT(0.1,-0.2,1/3) => -0.033333333333333

=RAWSUBTRACT(0.1,-0.2,2/7) => 0.014285714285714

So which one is closer to 0.3?

erAck··on Stencila: An open source office suite for reproducible research
As you referenced that bug and there also gave an example involving fractions and =0.1+0.2 you would certainly also agree that the binary floating point representation of =0.1+0.2-0.3 is not 0.0, still Excel displays 0 as result (and so does Calc) instead of 5.551115123125783E-17 because users expect that.

Your bit-level accuracy approach isn't as simple when it comes to user experience and Excel compatibility.

erAck··on GitLab Web IDE
Exactly. You don't want documentation editors having to learn git and all cumbersome processes first. They may not even want to learn that. They want to edit and get their changes in.

erAck··on Show HN: Tones.fm – Make synth music
This is fun, but (at least for me) there's awful scratch noise when each note's sound starts playing, which unfortunately doesn't make it enjoyable at all.
erAck··on Teacher in Ghana has no computers so he draws Microsoft Word on the blackboard
Understanding how to use any word processor is a job skill. LibreOffice supports Akan, an official language spoken in Ghana. Projects could translate the UI to Akan so even more people would be able to use it.
erAck··on Teacher in Ghana has no computers so he draws Microsoft Word on the blackboard
So you prefer to throw them into the MS mono culture pit.
erAck··on Teacher in Ghana has no computers so he draws Microsoft Word on the blackboard
He should teach LibreOffice Writer instead so when actually some laptops arrive at the school they wouldn't have to waste money on MS product licenses.

Nowadays it's more important to control and restrict outgoing connections than incoming connections. Who would had thought of that 25 years ago.
erAck··on Life in the age of noise
Well it's a Depeche Mode song quote, but the slogan is printed along with the shape of an island where I don't take a computer with me when I go there and turn on the phone only every other day or so or simply forget it. Being there is a completely different mind set and relaxing and for me that is the mental control to actively decide that no business or computer problem can bother me and ruin my day. Peace of mind.
